Does Metformin Have A Disease Modifying Effect In Symptomatic Knee Osteoarthritis? A Multicentre Randomised, Double-blind, Placebo-controlled Trial

Summary
Osteoarthritis(OA) is a major contributor to this disease burden. Currently, there is no therapy that slows disease progression. Metformin may affect OA progression via multiple pathways that address the pathogenesis of knee OA, including weight loss, glucose- and lipid-lowering, and anti-inflammation. This will be the world first randomised, double-blind controlled trial, to assess the effect of metformin, compared with placebo, on knee OA-related structural and clinical outcomes
Liver Cell Transplantation For The Treatment Of Liver Based Metabolic Diseases.

Summary
We propose to investigate the role of liver cell transplantation (LCT) for the therapy of inherited liver-based metabolic diseases using a methylmalonic aciduria (MMA) mouse model. LCT provides an exciting alternative to whole organ transplantation. Initially it was considered liver cells would be immunopriviledged. This has not proven to be the case. Immune modulation will be important. We will also examine immune modulation using antibodies to optimise longterm survival of allogeneic cells.
Development Of A New Surgical-guidance Tool For Intra-operative Tumour Margin Assessment In Breast Cancer

Summary
One third of breast cancer patients undergoing breast conserving surgery have insufficient tissue removed, resulting in an increased risk of recurrence. We have developed a high resolution optical imaging probe with the potential to detect small areas of cancer. It could be used to help guide the surgeon to remove all cancerous tissue from the patient. This grant will allow us to develop the probe to a stage that it can be used during surgery, and perform the world’s first clinical scans.
Development Of Microscope-in-a-needle Devices For Improved Clinical Diagnostics

Summary
We have developed a new high-resolution optical imaging technology. The unique aspect of our research has been to redesign the imaging probe, miniaturising it to a few hundred microns in diameter, and encase it in a hypodermic needle – a ‘microscope-in-a-needle’. We are developing specific imaging probes to aid in the assessment of lung disease; the diagnosis of liver disease; and integrated into a brain biopsy needle to enable safer brain biopsies.
Advances in positron emission tomography now allow specific pathological features of many brain diseases such as Alzheimer's disease to be measured with a brain scan during life. This Fellowship will assist Professor Rowe and his team in their world leading work on new PET scanning techniques to improve diagnosis and assist the development of treatment for Alzheimer's and other degenerative diseases of the brain.
Are Large Joint Osteoarthritis And Low Back Pain Metabolic Disorders?

Summary
While osteoarthritis (OA) is considered a “wear and tear” disease, there is evidence that OA may be related to a cluster of metabolic abnormalities including obesity, diabetes mellitus, hypertension and high cholesterol. Similarly, low back pain main be linked to a sedentary lifestyle and metabolic changes. This project will examine the relationship between metabolic derangements and back pain and large joint OA in an attempt to better understand these diseases and develop effective treatments.
Improving Human FMRI Through Modeling And Imaging Microvascular Dynamics

Funding Amount
$486,144.00
Summary
In this project we aim to establish a reliable vascular baseline to improve mapping of both small-scale functional architecture and large-scale brain networks in functional human brain mapping using MRI. By mapping the grey matter vasculature with high detail in both humans and animals, and by computing and matching of these atlases across species we will be able to validate this approach in vivo to confirm the better spatial specificity of the newly developed approach.

Metabolic factors and measures of inflammation in the body have recently been shown to influence mental function and increase the risk of developing age-related disorders such as Alzheimer’s disease.

The influence metabolic factors and inflammation have on function of the ageing brain is likely to be determined by complex interplay between many factors, such as physical health, lifestyle, nutrition and our genes. By studying these factors and how they relate to one another in large groups of elderly individuals, we will be able to determine the role these factors play in brain ageing. In addition we will be able to determine an ‘at risk’ profile for elderly individuals for accelerated ageing effects. Identification of this profile is important as it will allow the development of interventions which may prevent or delay the onset of cognitive decline in late life. We plan to study the impact of metabolic and inflammatory factors on brain ageing and in two groups of elderly individuals both of which are currently being studied in detail by our research team. By using these existing groups we will minimize the costs associated with our research, but maximize the research benefit and the benefit to society. Our groups include a large community sample of elderly individuals aged 70-90 years and a large group of elderly twins aged over 65 years. Our use of twins for the study is particularly important as it will help us separate genetic and environmental influences on the measures. We will measure multiple metabolic and inflammatory factors in the body and determine their relationship to detailed tests of cognitive function and to cerebrovascular pathology on brain magnetic resonance imaging. We will look at how these factors relate to one another and which factors are most strongly associated with accelerated ageing. We will be able to follow subjects in each group over a 2 year interval to see which factors most strongly predict change in cognitive function and cerebrovascular pathology over time. Our research is unique in its inclusion of multiple factors which may affect brain ageing, its ability to look in detail at the contribution of genetic influences on metabolic and inflammatory factors, and in our planned follow-up of these individuals.Read moreRead less
